Collectively, these form what is known as the exposure triangle. Get our FREE 52-weeks Photography E-Mail Course. So get outside and take some shots–just be prepared to use that EV feature! Simply put, exposure compensation is a quick way to adjust the exposure value (EV) of your camera’s metering system. Take a look at the below sample chart, where we will try to adjust exposure using exposure compensation in aperture priority mode: Dialing in -1 EV via exposure compensation will increase the shutter speed from 1/250th of a second to 1/500th of a second, while keeping the aperture constant: This essentially darkens the image, since there is less light hitting the sensor. So where do you find the exposure compensation feature on a camera? There will be an indicator on the scale that shows where the exposure compensation adjustment is. However, unless I am missing something, I do not understand why all four tables illustrating the effect of exposure compensation are all exactly the same, except for the headings? To address this problem, I used the Exposure Compensation feature of my camera and dialed +1 EV (Exposure Value), which resulted in a much brighter image: The image is now properly exposed, with the whole scene appearing much brighter compared to what the camera thought was the right brightness. The difference between the tables is the table cell background colour: each row has one cell that is darker than the others. Because of such advancements, our cameras might require less and less manual intervention by using the exposure compensation feature. That said, note that it’s tough to be certain about exposure compensation, because modern cameras have complex metering algorithms that deal with light and dark situations. changing one or more of the exposure values that make up the image Thanks so much for pointing that out–I’ve fixed it , Your email address will not be published. Make a note which exposure you find best and in so doing learn how your camera reads light. If an image appears to be dark, you dial a positive number (+EV), whereas if the image appears to be bright, you dial a negative number (-EV). Exposure compensation is an easy way to correct for improper exposure. Reading about technique is one thing. Cameras frequently overexpose dark subjects. Then, selecting a positive compensation value will bias toward over-exposure, or a negative value will bias toward under-exposure. Alternatively, with the exposure compensation function, you can stay in auto mode but can tell the camera to allow more light in, often by increments of one-third of a stop. So you can never know for certain that your camera is going to overexpose or underexpose–just when it probably will! It is a "sliding scale" found on most digital cameras, usually indicated with a "plus/minus" sign and a sliding scale, usually ranging from -2.0 on the left to +2.0 on the right. I am trying to figure out if I should stick to the Program auto exposure mode, or should I use full manual mode. It explains what it is, as well as when and where you might want to use it. In this situation, it pays to dial in a bit of positive exposure compensation. Today's question from Jeff S. -- “How does exposure compensation actually work? Dial in some negative exposure compensation to keep the photo sufficiently dark. Most mid-range cameras with manual-controls and a single control-dial use this to their advantage where the EC button switches between controlling aperture and shutter-speed in Manual mode. It can involve adding a bit of exposure compensation, then taking a photo, then adding a bit more, then taking a photo, and so on. You can also use deliberate underexposure to create a darker, moodier effect. You can use exposure compensation when shooting with Aperture Priority mode, Shutter Priority mode, or Program mode. No, you cannot use exposure compensation with Manual mode. So what is exposure compensation? The video’s host, David, also goes on to demonstrate how it can help with a potentially difficult subject. Other times, your camera will get the exposure wrong in consistent ways. And that’s okay. Exposure compensation is a technique for adjusting the exposure indicated by a photographic exposure meter, in consideration of factors that may cause the indicated exposure to result in a less-than-optimal image.Factors considered may include unusual lighting distribution, variations within a camera system, filters, non-standard processing, or intended underexposure or … However, no matter how intelligent our cameras are going to get, knowing how to quickly make exposure adjustments is still important, not just because you might need to use it one day, but also because you can push the limits of your camera by taking advantage of such techniques as exposing to the right. Exposure to Toxins at Work: Workplace Exposure Claims. You misunderstand how exposure compensation works. You can also use exposure compensation for an artistic effect (if you want a photo that’s dark and moody, or bright and airy). Most cameras allow up to 2 stops of exposure compensation, where each stop provides either a doubling or halving of light compare… Then continue to make changes until you nail the exposure. This is negative exposure compensation, and it will cause your camera to darken the photo. If your subject is really dark, like a pitch-black rock, you can start out with a value of -2. And the – symbol indicates decreased brightness. There are certain situations when using Manual mode (as opposed to Programmed Auto, Aperture Priority or Shutter Priority with exposure compensation) is beneficial. But just be careful and make sure to check the exposure on your camera’s LCD. But in understanding these two situations, we’ll get a much clearer view of what Flash Exposure Compensation does.

Before we show you where you can find the exposure compensation feature on your camera, let’s explore what it does and in what camera modes the feature can be used. You should dial in +1 exposure compensation, take a photo, and review it on the LCD. Using the exposure compensation dial will only make a difference if you're in one of the P, A or S auto-exposure modes. These days, if I was using manual mode and felt that the cameras “opinion” needed correction it wouldn’t even occur to me to look for an Exposure Compensation control, I would simply change aperture or shutter speed directly – or, if I remembered, ISO – and what a luxury that is! Rim Light Photography: The Ultimate Guide, How to Edit Photos in Snapseed: The Ultimate Guide. Well put simply it allows you to incrementally adjust the camera’s exposure around the default reading that meter is giving. Let’s take a look at an example, where my camera’s metering system did a poor job at properly exposing the scene: While shooting in Aperture Priority mode, the camera’s meter ended up underexposing the image, because the scene was rather challenging – the sky and the white sand in the foreground were bright, so the camera ended up darkening the whole image, which resulted in my subjects in the scene appearing way too dark. For example, if the camera is in Aperture Priority Mode, the camera, by use of its TTL Light Meter will automatically select the Shutter Speed. Identifying the exposure compensation button on a camera is pretty easy – look for a button that has plus and minus signs, similar to the following illustration: And if you cannot find such a button, there might be a dial on the top or the back of the camera that goes from a negative value to a positive value, such as -3 to +3, with small increments in between. Exposure Compensation allows photographers to override exposure settings picked by camera’s light meter, in order to darken or brighten images before they are captured. And my pics were all underexposed ? A nice article, clear and well illustrated! Please CTRL+F5 to force the refresh of the page and its images and the updated image should now be fixed.

Full Frame Vs Crop: What’s the Difference and Why Does It Matter? In Manual, you set the ISO, aperture, and shutter speed yourself. So here’s a basic step by step process for using exposure compensation: First, you take a photo, letting the camera’s meter do the exposure work. This is where Exposure Compensation comes into play, with photographer manually taking control of the brightness of the image and overriding it using the exposure compensation feature of the camera.
